HYD RANT.

SPECEICATIN forming part of Letters Patent N o. 546,075, dated September 10, 1895.

Application filed March 11.1895.

To all whom, it concern.-

Be it known that I. Jeux G. MURDock,a citizen of the United States,and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in llydrants, of which the following is a specication.

My invention relates to an improvementiu hydrants, street-washers, the. Its objects are to provide a hydrant having` its valve so arranged that the valve and its connections may be readilywithdrawn at any time, repaired, and replaced, or a new valve supplied without necessitating the digging up of the hydrant, and also to provide a coupling for the stock whereby the nipple for making the connection with the water-supply pipe may be readily adjusted to bring,r it in any position desired relative to the dischargespout, in order to avoid the necessity of multiplicity of bases for the hydrant-stock, having,r nipples projecting in diterent. radial lines, so as to have a direct connection with the pipe leading from the water-main without the necessity of bending the pipe around, if made oflead, or of using elbows or couplings to accommodate the connection between the main and supply-pipe of the hydrant.

The invention also consists in minor details of construction, all of which will be first fully described in connection with the accompanying drawings, and will `be then particularlyr referred to and pointed out in the claims.

Referring to the drawings, in which like parts are indicated by similar reference-let ters wherever they occur throughout the varions views, Figure 1 is a longitudinal diametrical section of a hydrant provided with my improvements, the central portion of the stock and supply-pipo being broken away and the valves being shown in the closed position- Fig. 2 is a diametrical section of the valve and its connections, the valve being shown in the open position. Fig. 3 is au invetted plan view of the cylindrical shell which carries the valve, the neck being screwthreaded to receive the dischargeconduit.' Fig. 4 is a plan view of the loose or removable valve-seat. Fig. 5l is a diametrical sectional view of the coupling which connects the stock with its base or support. Fig. 6 is a plan view of the base which supports the stock and through which one branch of the elbow which connects the supply-pipe of the Serial No.541.263. (No model.l

screw-threaded shaft A2, by which the head.

l, which carries the movable water-way b and the discharge-spout b', is elevated or lowered to open or close thehydrant. The spout b' passes a vertical slot in the head and through a slideorescutcheou b`,and is screwed into the movable-way carrier C is the body of the hydrant-stock.

The parts above referred to are of ordinary construction, and need not therefore be particularly described.

The stock C, which is preferably of wrought metal, is screwed into the head A at its upper end, and at its lower end is firmly united by screw-threaded connection with a ring I), (shown upon an enlargedscale in l"ig.5,) which, when united to the stock C, forms practically an integral part of it. The ring D has a reduced neck dto fit and turn in the upper end of the base E. (Shown in plan view upon an enlarged scale in Fig. 6.) The ring D has also an inwardly-projecting flange d' at its lower end, to serve as a seat. for the annular disk or tlangef, formingr a part of the elbow F, which connects the waterway of the stock with the pipe leading from the water-main. The elbow union F has also projecting downwardly from ita screw-threaded shaft f', which passes centrally through the web or dividing-partitione of the base E, the base E being slotted upon one side, as shown at E', to allow the elbow to pass down and rest. upon the web or partition, to which itis secured bya nut fi. It. will thus be seen that when the base E is coupled to the ring D by the nutf2 the base E may be turned around to any position desired, and the nipple f3, which is coupled to the elbow F by coupling f* in the usual manner,can be brought. iu any position relativo to the discharge-spout b. The ring D has projecting laterally from it lugs (F to receive a Spanner, by which the ring is rmly screwed onto the lower end of tho stock C.

The vertical branch of the elbow union l" has screwed into it a. nipple G, provided with an angular wrench-seat g, for t-he purpose of screwing it firmly in place. The upper portion g of the nipple is slightly taperi g and dressed off true exteriorly to form a slipgjoint with the plunger secured to the lower end of the water-way b. The upper end g of the nipple is also dressed out true and slightly flaring to receive the tapered nipple or down` ward extension h of the loose valve-seat. Il.

The plunger, which is secured to the bottom of the water-way b, consists of a cylindrical shell I and the parts carried by it,which will now be described. The reduced neck i of the shell is tapped to receive the lower screw-threaded end of the pipe b. There is also formed integral with the shell I a disk i', which is united to the shell by webs F, leaving a water-way between the disk and interior of the shell. To the under side of this disk is secured the elastic valve P by a screw passing centrally through it and tapped into the disk vi. To the lower end of the shell I is united by screw-thread connection the shell J, which has an inwardLv-projectingannular flange, upon which is seated a cup leather packing j, held in place by a metal ring j', which is forced upon the cup leather packing by the lower end of the `shell I when the partsare united, as shown in Figs. 1 and 2.

The opening in the shell J is dared or coneshaped, so as to guide the plunger over the tapered end g of the nipple G, and the lower edge is diametrically gro )ved at jl to receive a key or wrench, by which the shell .l is secured firmly in place on the lower end of the shell I. The iinished portion g' of the nipple has a wasteway g2, which is uncovered when the valve is seated to allow the waste water in the pipe orwater-way b to drain outand pass olf through the base E, the lower end of which may, if desired, be connected to a waste or drain pipe or set upon a foundation of broken stone or coarse gravel, so that the waste water may pass away through the ground.

The principal cause of leakage in hydrants is the cutting away of the valve-seat by gritty substances in the water, and when it was found that the hydrant was leaking it was necessary to dig it up or remove the whole of it. in order to reach the seat to repair it or replace it with a new one. In some cases the seat was screwed into the water-way and it was diicult to remove it without digging up the hydrant, and also diliicult to replace it on account of the sand or other stuff interfering with the screwthreaded connection and preventing a close joint. By means of my invention it is only neceary to remove the. spout b' and take olt' the cap A', when the valve and its seat and all the parts that are liable to wear may be withdrawn, repaired, or replaced by a .new part and the plunger and water-way quickly replaced.

What I claim is- 1. The combination of the stock, the water way within the stock having a spout extending through the head of the stock, the base fitted to turn upon the lowerend of the stock and having a centrally perforated dividing partition, the elbow leading from the main passing through the rim of the stock and having a downwardly extending screw threaded projection to pass through the dividing partition of the base and connected to the waterway of the stock, and a nut fitted to the downwardly extending screw threaded end of the elbow, whereby the supply port for the water to the stock may be adjusted relative to the discharge spout and locked in the desired position, substantially as and for the purpose set forth.

The combination of thc stock, the base, the water su pply elbow in the base and lower end of the stock, the nipple secured in the supply elbow and projecting centrally up into the stock, having its upper end finished and tapering to form a slip joint with the movable water way, the movable waterway, the plunger secured to the lower end thereof to pass over the nipple projecting up from the water way. the packing ring to form a joint with said nipple, the loose valve seat within the plunger, having downwardly extending tapered end to form a joint with the upper end of the nipple, a valve carried by the plunger, and means such as shown to elevate the valve from its seat and close it thereon, substantially asshown and described.

3. In a valve mechanism for hydrants, the combination of the supply nipple projecting centrally from the lower end of the stock and tapered exteriorly at its upper end, the chambered plunger fitted to slide over the tapered portion of the nipple, a packing with-I in the plunger to form a water joint with the nipple, a loose valve scat within the chamber, having a cylindrical, tapered downward e.vtension to fit in the nipple and the valve carried by the plunger to close upon the seat when the plunger is forced downwardly, and open the water way when the plunger is elcvated, substantially as shown and described.

t. The combination of the hydrant stock, the movable water way fitted to slide vertically in said stock, means for elevating and lowering said water way, the ring, I), having a reduced lower neck, il, and inwardly extending flange, d', secured to the lower end of the stock, the base, E, to receive the reduced neck, d, of the ring, D, and support the stock, the elbow or union, F, having an annular tiange,f, resting upon theiuwardly projecting liange,d, of the ring, D, the nipple, G, secured in the vertical brauch of the union, F, and having a tapered upward extension, g', the chambered plunger carrying the valve mechanism within it and adapted to slide over the tapered end of the nipple and secured to the lower end of the movable water way, substantially as shown and described.
